Avertissement

Ce billet a la pure intention de vous inciter à suivre les formations Intro Kanban et Kanban Avancé de Daniel Vacanti qui se tiendront à Montréal et Québec à la mi-novembre.

Si vous croyez tout savoir à propos de Kanban (comme moi dans l’temps), je vous encourage à lire ce billet jusqu’à la fin. La formation de Daniel Vacanti en mai dernier m’a permis de devenir meilleur dans ma mise en application de Kanban.

J’aimerais donc vous partager les notes que j’avais conservées lors de a formation:

• If work is piling up, ask the customer to stop.

• A shorter cycle time gives a shorter feedback loop.

• Achieve self-improvement in your team by using cycle time. 

• Spending more time estimating, means spending less time doing the work.

• To get more done, work on fewer things at once.

• Focus on the workflow versus the roles.

• WIP is the biggest influencer of cycle time and throughput.

• How much will it cost? as a function of how long it will take.

• Kanban board = Reality board

• The key insight of Lean is that inventory is perishable. It is not an asset. It is a liability.

• Policies are helpful when it comes to handling variability.

• When work is piling up, move the WIP down. 

• The flow is more predictable if we can throttle the input and output of my Kanban system.

• The backlog column doesn’t have a WIP Limit, so it’s not considered part of the Kanban system.

• An expedite process kills your predictability. You have to set the bar high to get into the Expedite lane.

• Rename the Expedite Lane, switch to Flow Destroyer Lane.

• Stair steps on CFD are indicative of batch work.

• 11-12 dots with a good management of WIP Limit to have a good scatterplot.

• Drive out uncertainty by doing the work.

• Queue replenishment meeting = Sprint planning.

• Handoffs is the way known to create columns.

• 2-tier Kanban board: Workflow within workflow.

• Bigger epics are sagas, legends and bibles.

Si certaines phrases vous paraissent floues ou incompréhensibles dans la liste précédente, c’est peut-être un signe qu’il reste certaines zones à explorer dans votre connaissance Kanban. Personnellement, je crois que vous avez le meilleur prof Kanban, Daniel Vacanti, pour vous aider à grandir avec cette organisation du travail.

Après avoir lu l’excellent excellent excellent livre Actionable Agile – Metrics for Predictability de Daniel Vacanti, j’aimerais vous partager les 10 meilleures citations du livre.

1. Delay is the enemy of flow.

2. Remember that being predictable is not completely about making forecasts. The bigger part of predictability is operating a system that behaves in a way that we expect it to.

3. Kanban cannot work because there are no commitments. Nothing could be further from the truth. It is just that the approach to commitment is very different than, say, Scrum.

4. The first thing to know about variation is that it will always exist.

5. Think about all the time you have wasted in your life doing estimation. Think about all the time wasting in « pointless » debates of whether a story is a two points or three points. Using these percentiles is a means to get rid of all that. Measuring to get an SLA allows us to adopt a much lighter approach to estimation and planning.

6. If a team follows all of the principles presented in this book, then the SLA can be used as a substitute for many upfront planning and estimation activities.

7. Use your Scatterplot’s percentiles to collaborate with your customers in choosing a Service Level Agreement (SLA) for your process.

8. Predictability is the ability to make a quantitative forecast about a process’s future state.

9. A forecast is a calculation about the future completion of an item or items that includes both a date range and a probability.

10. Whenever uncertainty is involved then a probabilistic approach is necessitated.

11. The older a work item gets, the greater chance it has of aging still more.

12. The second reason is that CFDs (Cumulative Flow Diagram) are for looking backward.

Je sais. Il y en a 12 finalement. Honnêtement, j’ai pris plus de 50 notes dans cet excellent excellent excellent livre. Je me suis arrêté après 12 mais j’aurais pu facilement vous les beurrer ici, vous auriez trouvé ça trop long pis seriez retournés sur Facebook regarder des photos de chats.

By the way, Vacanti sera au Québec dans la semaine du 14 novembre pour donner ses cours Kanban. Le 14 novembre, il donne le cours Kanban Avancé à Québec. Et les 17 et 18 novembre, il sera à Montréal pour donner son cours Intro Kanban. Des formations incroyables à ne pas manquer pour toute personne qui désire monter en compétences avec cette approche.

Bonne lecture!
